<h2>Type Asserts (NUnit 2.2.3 / 2.5)</h2>

<p>These methods allow us to make assertions about the type of an object.</p>

<div class="code" style="width: 36em" ><pre>

Assert.IsInstanceOfType( Type expected, object actual );
Assert.IsInstanceOfType( Type expected, object actual, 
                string message );
Assert.IsInstanceOfType( Type expected, object actual, 
                string message, params object[] parms );
				
Assert.IsNotInstanceOfType( Type expected, object actual );
Assert.IsNotInstanceOfType( Type expected, object actual, 
                string message );
Assert.IsNotInstanceOfType( Type expected, object actual, 
                string message, params object[] parms );
			
Assert.IsAssignableFrom( Type expected, object actual );
Assert.IsAssignableFrom( Type expected, object actual, 
                string message );
Assert.IsAssignableFrom( Type expected, object actual, 
                string message, params object[] parms );
				
Assert.IsNotAssignableFrom( Type expected, object actual );
Assert.IsNotAssignableFrom( Type expected, object actual, 
                string message );
Assert.IsNotAssignableFrom( Type expected, object actual, 
                string message, params object[] parms );
				
</pre></div>

Beginning with NUnit 2.5, generic equivalents are available 
in .NET 2.0 NUnit packages.

<div class="code" style="width: 36em" ><pre>

Assert.IsInstanceOf&lt;T&gt;( object actual );
Assert.IsInstanceOf&lt;T&gt;( object actual, string message );
Assert.IsInstanceOf&lt;T&gt;( object actual, 
                string message, params object[] parms );
				
Assert.IsNotInstanceOf&lt;T&gt;( object actual );
Assert.IsNotInstanceOf&lt;T&gt;( object actual, string message ); 
Assert.IsNotInstanceOf&lt;T&gt;( object actual, 
                string message, params object[] parms );
			
Assert.IsAssignableFrom&lt;T&gt;( object actual );
Assert.IsAssignableFrom&lt;T&gt;( object actual, string message );
Assert.IsAssignableFrom&lt;T&gt;( object actual, 
                string message, params object[] parms );
				
Assert.IsNotAssignableFrom&lt;T&gt;( object actual );
Assert.IsNotAssignableFrom&lt;T&gt;( object actual, string message );
Assert.IsNotAssignableFrom&lt;T&gt;( object actual, 
                string message, params object[] parms );
